WE KNOW THAT WE COULD LENGTHEN THE DURATION THE SUN IS VISIBLE OVER A REGION BY TEMPORARILY SLOWING THE EARTH AS IT SPINS. STOPPING THE SUN FROM MOVING, HOWEVER, WOULD HAVE NO EFFECT. THUS, IN TRYING TO DETERMINE IF MUHAMMAD KNEW THAT THE EARTH ROTATES ON ITS AXIS, THE FOLLOWING EXCERPT OF SAHIH BUKHARI 4:53:353 (FULL HADITH HERE) IS HELPFUL. AS WE READ THE EXCERPT BELOW, WE CAN ASK OURSELVES, "DID MUHAMMAD THINK THAT THE SUN GOES AROUND THE EARTH?"Narrated Abu Huraira:The Prophet [Muhammad] said, "... So, the prophet carried out the expedition and when he reached that town at the time or nearly at the time of the 'Asr prayer, he said to the sun,'O sun! You are under Allah's Order and I am under Allah's Order O Allah! Stop it (i.e. the sun) from setting.' It was stopped till Allah made him victorious."
